The 18O was very stable between 0h and 2h around I ~ 4.5 ľA.
CAVIAR ~ 161k; CATS1 ~ 88kcps; CATS2~ 111kcps ; CHIO ~ 106kcps; PLASTIC ~ 105 kcps.
The dead time is between 4 and 7%.
It was slowly decreasing to 3.7ľA at 2h45.
Between 2h48 and 3h we see strong fluctuations of the primary beam current I down to 3.7ľA and to 0.5ľA.
We call the PCP machine, they tell us that they manage to recover the beam, and that there are strong instabilities at the source.
At 3h15 the beam is stable again, around 4.2ľA.

Between 4h-4h50 the 18O has decreased from 4.5 down to 4 ľA.

The dead time is between 4 and 7%.
The run 374 is stopped at 5h01 because the PCP machine is retuning
the beam intensity. The intensity was strongly decreasing at 4h50 down to 3ľA and then below 3ľA at 4h55.

The tuning of the beam alignment was checked by the PCP. cf beam profiles at 5h15 in LISE notebook and below.
We check also the beam profiles on CATS.
The beam was at 4.2 ľA increasing to 4.6 ľA but we do not recover the same intensity in LISE as during the run 374.
CAVIAR now at 90kcps and CATS2 around 53kcps (at 5h25).
6h50 CAVIAR 95 kcps CATS1: 51 kcps; CATS2: 64 kcps
The transmission to LISE seems to be not as good as before.
The beam on target is de-centered both on X (X +0.4mm) and Y (Y by ~ -2.4mm)

Hi,
Thanks for looking into it. We made quite a lot of change in the analysis yesterday. There was several mistake and especially one on cats inverting X axis, so all angle were wrong previously.
Also the energy loss in the target is setup for 3He, so you expect the 3H line to show at a higher energy than it should ! Sounds good! |

Separation for Z=3&4 with CHIO(analog) + plastic is difficult so Z=4 gate may include Z=3&4.

For MM6 (left), a locus for punch-through is seen maybe because CsI veto gate is not so good.
